Pokémon Mystery Dungeon - Adventure Squad Series - WiFi Events

As of today, several new WiFi Events have begun in Japan for the Pokémon Mystery Dungeon Adventure Squad series. First is the WiiConnect24 event that allows Darkrai to appear in several of the dungeons. This event is running until September 12th.
